About

The bariatric surgery is recognized, at present, as the only effective therapeutic for the patients with morbid obesity. Two surgical procedures (said restrictive) are considered as consensual: the adjustable calibrated horizontal gastroplasty under laparoscopy (ring périgastric) and Gastric Bypass under laparoscopy (LGBP). The longitudinal gastrectomy (sleeve gastrectomy) is a technique of bariatric surgery recently validated (HAS on 2008). It consists of the realization of a partial gastrectomy of 2/3 (Fundus, gastric Body +/- antrum). However, lot of technical disagreements are brought back by expert teams. The most important disagreement concerns the conservation or the exeresis of the gastric antrum. In fact, the conservation of gastric antrum could facilitate the gastric emptying and to decrease the RGO (main complication) and act on the regulations of hormones modulators of the insulino-secretion.

A prospective,randomized study comparing these both techniques is necessary to determine a unique consensual technique

Full description

The main objective of this study is to compare the frequency of post-operative gastronomic appearance of gastroesophageal reflux(RGO) between two techniques of longitudinal gastrectomy under laparoscopy (gastrectomy coupling sleeve with antrum conservation or without antrum conservation) at patients with morbid obesity.

There are lot of secondary outcomes assessed in this study. In fact, one of secondary objectives is to compare between both techniques of longitudinal gastrectomy under laparoscopy described in the literature the efficiency on the loss of weight and global post-operative morbidity.

This study assess the impact of these surgery techniques on the comorbidity of the obesity and their treatments (type 2 diabetes, arterial hypertension, sleep apnea syndrome, arthralgia, dyslipemia).
